CVE-2025-31324Known exploitationPublic exploitNetwork attack vector

Unauthenticated code execution via unrestricted executable upload

Published Apr 24, 2025 · Updated Aug 4, 2026

Unrestricted file upload in SAP NetWeaver Visual Composer VCFRAMEWORK 7.50 allows remote attackers to execute code without authentication. The Metadata Uploader endpoint accepts executable binaries without an authorization check and places them in web-executable server paths. Network access to that endpoint is sufficient; uploaded JSP web shells execute with the SAP service account and can compromise the host.
